You could use XYRemap, but I also already wrote Widen for this exact purpose, which works in all 8-bit colour spaces (but is 64-bit only).
If you're looking for a formula, it involves tan or inverse tan, can't remember which way round I did it. You could also try messing around with Defish which may mitigate the ugliness of edge distortion on pans by introducing some vertical distortion as well.

If I use an RGB24 image as distortion map (a.k.a. look-up table), the resolution of the distortion would be 8 bit at most. I guess it might be coarse enough to see some "motion banding" in panning scenes?!
